TECHNICAL FIELD

The present disclosure pertains to the use of propofol prodrugs, pharmaceutically acceptable salts of propofol prodrugs, or mixtures thereof, to treat disease or disorder, including migraine.

The present disclosure also pertains to the use of fospropofol, pharmaceutically acceptable salts of fospropofol, or mixtures thereof, to treat migraine.

The disclosure also pertains to pharmaceutical compositions for oral administration of fospropofol, or pharmaceutically acceptable salts of fospropofol, well as methods for oral administration of fospropofol.

BACKGROUND

Propofol (2,6-diisopropylphenol) is an intravenous short-acting anesthetic agent that has gained acceptance for inducing and maintaining anesthesia and for procedural sedation. Propofol is a highly lipophilic drug which must be formulated as a suspension with a lipid carrier in aqueous medium. Consequently, propofol derivatives were developed which possessed increased water solubility to simplify formulation. One of these was fospropofol ((2,6-diisopropylphenoxy)methyl dihydrogen phosphate). Fospropofol is a water-soluble, phosphono-O-methyl prodrug of propofol that was approved in the United States as an alternative to propofol for monitored anesthesia care during procedures.

While intravenous administration is useful for anesthesia applications, oral administration of fospropfol would be desirable for other uses. Oral dosing, however, requires a dosage form having adequate bioavailability with minimal subject-to-subject variability. Thus, there is a need for dosage forms of fospropofol that are orally bioavailable with minimal inter-subject variability.

Fospropofol is rapidly metabolized by endothelial alkaline phosphatases to release propofol, phosphate, and formaldehyde. The small amount of formaldehyde is rapidly converted to formate and safely eliminated, similar to the other available phosphate methyl prodrugs such as fosphenytoin.

Migraine is a primary headache disorder characterized by recurrent headaches that may be moderate or severe. Typically, the headaches affect one half of the head, are pulsating in nature, and last from two to 72 hours.

Migraines are called primary headaches because the pain is not caused by another disorder or disease such as a brain tumor or head injury. Symptoms of migraines may include nausea, vomiting, and sensitivity to light, sound, or smell. The pain is generally made worse by physical activity. Some cause pain on just the right side or left side of the head, others result in pain all over. Migraine sufferers may have moderate or severe pain and usually can't participate in normal activities because of the pain. Often when a migraine strikes, people try to find a quiet, dark room.

Many people have an aura with a migraine, typically a short period of visual disturbance that signals that the headache will soon occur. Sufferers have reported seeing flashes or bright spots. Occasionally, an aura can occur with little or no headache following it.

The range of time someone is affected by an attack is often longer than the migraine itself, as there is a pre-monitory, or build-up phase, and a post-drome phase that can last one to two days. Different people have different triggers and different symptoms.

Migraines are believed to be due to a mixture of environmental and genetic factors. Genomics of migraines have been examined and certain gene mutations have been associated with severe migraines, but the etiology is presumably polygenic. Changing hormone levels may also play a role, as migraines affect slightly more boys than girls before puberty and two to three times more women than men after puberty. Catemanial migraine is not uncommon in women associated with the menses.

Migraines are believed to involve the nerves and blood vessels of the brain. However, older ideas that migraines were principally vascular in nature are now considered to be incorrect. Although an exact cause is unknown, brain scans show that migraines may be due to “hyperactivity” in parts of the brain. This activity can spread across the cortex during the course of the migraine, which is known as spreading cortical depression.

Migraines are one of the most common causes of disability. There are about 100 million people with recurrent headaches in the U.S. and about 37 million of these people have migraines. The World Health Organization suggests that 18 percent of women and 7 percent of men in the U.S. suffer from migraines. Globally, approximately 15% of people are affected by migraines. Migraines most often start at puberty and get worse during middle age. In some women, migraines become less common following menopause. Migraine headaches are a common cause of disability in the United States, affecting approximately 27 million American adults, or 17.1% of women and 5.6% of men.

There is often a distinction between a migraine with an aura and a migraine without an aura. The most current terminology defines a classic migraine as a migraine with an aura and non-classic or common migraine as a migraine without aura. Also, there is often a distinction between chronic migraine and episodic migraine. Chronic migraine, which affects 3.2 million Americans (2%), is defined as having at least 15 headache days a month, with at least 8 days of having headaches with migraine features, and for longer than 3 months in duration. Episodic migraine, in contrast, is a condition defined as having fewer headache days or fewer headache days with migraine features per month.

Migraine treatment may also be characterised as acute treatment or prophylactic (i.e., preventative) treatment. In some embodiments, the methods and pharmaceutical compositions disclosed herein are useful for acute treatment of migraine. In some embodiments, the methods and pharmaceutical compositions disclosed herein are useful for acute treatment of migraine with or without aura. In other embodiments, the methods and pharmaceutical compositions disclosed herein are useful for prophylactic treatment of migraine.

Current treatments for migraine are divided into acute, abortive agents (analgesics, triptans, ergots, etc.), and medications that are used chronically to will reduce the frequency and severity of migraine attacks.

Initial recommended treatment is with one of the acute treatments, such as ibuprofen, naproxen sodium or acetaminophen. Caffeine may also be used for treatment. Nausea medications may also be administered.

Triptans and dihydroergotamine (DHE-45) are also commonly used acute treatments. The oral triptans [sumatriptan (Imitrex), naratriptan (Amerge), zolmitriptan (Zomig), rizatriptan (Maxalt), almotriptan (Axert), frovatriptan (Frova), and eletriptan (Relpax)] are thought to be generally effective in only 60 to 70% of patients. Lasmiditan (Reyvow), an oral ditan related to the oral triptans, is used in a similar fashion to the triptans and has similar efficacy. A large percentage of migraine sufferers are either resistant to these medications or they have unacceptable side effects.

Various NSAID drugs other than ibuprofen and naproxen may also be used for acute treatment, such as diclofenac and ketorolac. Opiates are generally ineffective and are contraindicated.

Calcitonin gene related peptide (CGRP) receptor targeted small molecules such as ubrogepant and rimegepant are newer acute treatments but they are generally less effective than the triptans although they are better tolerated.

Many patients require chronic (daily) therapy to prevent migraine attacks. The antidepressant and mood stabilizer Amitriptyline is quite effective in some patients, as are beta-blockers including propranolol and metoprolol, as well certain antiseizure drugs including topiramate, valproate, and gabapentin.

Antibodies that act on CGRP or its receptor are now also widely used as preventives. They include Aimovig® (erenumab), Emgality® (galcanezumab), Ajovy® (fremanezumab), and Vyepti (eptinezumab). Although these agents are effective in many patients, there are many in whom they are ineffective. Furthermore, being recombinant biologicals, they are expensive, and because they are proteins they must be administered by injection, which does not appeal to some patients.

Quilipta™ (atogepant) along with rimegepant are small molecule CGRP receptor antagonists that are used chronically, like CGRP antibodies, as preventives. They are no more effective than the antibodies and many patients continue to experience unacceptable migraine attacks.

Thus, there is a need for additional methods of treating migraine, particularly refractory migraine.

DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

The present disclosure may be understood more readily by reference to the following detailed description of desired embodiments and the examples included therein. In the following specification and the claims that follow, reference will be made to a number of terms which have the following meanings.

Unless indicated to the contrary, the numerical values should be understood to include numerical values which are the same when reduced to the same number of significant figures and numerical values which differ from the stated value by less than the experimental error of conventional measurement technique of the type described in the present application to determine the value.

All ranges disclosed herein are inclusive of the recited endpoint and independently combinable (for example, the range of “from 2 to 10” is inclusive of the endpoints, 2 and 10, and all the intermediate values). The endpoints of the ranges and any values disclosed herein are not limited to the precise range or value; they are sufficiently imprecise to include values approximating these ranges and/or values.

As used herein, approximating language may be applied to modify any quantitative representation that may vary without resulting in a change in the basic function to which it is related. Accordingly, a value modified by a term or terms, such as “about” and “substantially,” may not be limited to the precise value specified, in some cases. In at least some instances, the approximating language may correspond to the precision of an instrument for measuring the value. The modifier “about” should also be considered as disclosing the range defined by the absolute values of the two endpoints. For example, the expression “from about 2 to about 4” also discloses the range “from 2 to 4.” The term “about” may refer to plus or minus 10% of the indicated number. For example, “about 10%” may indicate a range of 9% to 11%, and “about 1” may mean from 0.9-1.1. Other meanings of “about” may be apparent from the context, such as rounding off, so, for example “about 1” may also mean from 0.5 to 1.4.

In the present disclosure the singular forms “a,” “an,” and “the” include the plural reference, and reference to a particular numerical value includes at least that particular value, unless the context clearly indicates otherwise. Thus, for example, a reference to “a compound” is a reference to one or more of such compounds and equivalents thereof known to those skilled in the art, and so forth. The term “plurality”, as used herein, means more than one.

Certain features of the disclosure which are, for clarity, described herein in the context of separate embodiments, may also be provided in combination in a single embodiment. That is, unless obviously incompatible or specifically excluded, each individual embodiment is deemed to be combinable with any other embodiment(s) and such a combination is considered to be another embodiment. Conversely, various features of the disclosure that are, for brevity, described in the context of a single embodiment, may also be provided separately or in any sub-combination. Finally, while an embodiment may be described as part of a series of steps, each said step may also be considered an independent embodiment in itself, combinable with others.

“Propofol prodrug”, as used herein, refers to a molecule which, when administered to a mammal, is converted in vivo to propofol.

As used herein, “propofol” refers to 2,6-diisopropylphenol, which has the structure:

As used herein, “fospropofol” refers to (2,6-diisopropylphenoxy)methyl dihydrogen phosphate, which has the structure:

The terms “fospropofol disodium”, or “disodium salt of fospropofol” refer to the compound having the structure:

The phrase “propofol prodrug, a pharmaceutically acceptable salt of propofol prodrug, or mixtures thereof” is meant to encompass a propofol prodrug alone, a pharmaceutically acceptable salt of propofol alone, mixtures of two or more pharmaceutically acceptable salts of a propofol prodrug, and mixtures of a propofol prodrug and one or more pharmaceutically acceptable salts of a propofol prodrug.

The phrase “fospropofol, a pharmaceutically acceptable salt of fospropofol, or mixtures thereof” is meant to encompass fospropofol alone, a pharmaceutically acceptable salt of fospropofol alone, mixtures of two or more pharmaceutically acceptable salts of fospropofol, and mixtures and fospropofol and one or more pharmaceutically acceptable salts of fospropofol.

As used herein, “pharmaceutically acceptable salt of fospropofol” refers to a salt of fospropofol that is pharmaceutically acceptable and that possesses the desired pharmacologic activity. Such salts are generally non-toxic, and may be inorganic or organic base addition salts. Specifically, such salts include: salts formed when at least one acidic proton present in fospropofol either is replaced by at least one metal ion, e.g., an alkali metal ion, an alkaline earth ion, or an aluminum ion; or by an organic base such as aliphatic, alicyclic, or aromatic organic amines, such as ammonia, methylamine, dimethylamine, diethylamine, picoline, ethanolamine, diethanolamine, triethanolamine, ethylenediamine, lysine, arginine, ornithine, choline, N,N′-dibenzylethylene-diamine, chloroprocaine, diethanolamine, procaine, N-benzylphenethylamine, N-methylglucamine piperazine, tris(hydroxymethyl)-aminomethane, tetramethylammonium hydroxide, and the like. Examples of pharmaceutically acceptable salts of fospropofol include monosodium, monopotassium, disodium, dipotassium salts, diethylamine, t-butyl amine, ethylene diamine, benzathine, piperazine, ethanolamine, diethanolamine, ammonium, tromethamine, benethamine, histidine, calcium, magnesium, and zinc salts. Other exemplary salts include the meglumine, deanol, hydrabamine, 2-diethylaminoethanol, 4-(2-hydroxyethyl)-morpholine, 1-(2hydroxylethyl)-pyrrolidone, or imidazole.

A crystal form may be referred to herein as being characterized by graphical data “as shown in” a Figure. Such data include, for example, powder X-ray diffractograms (XRPD), Differential Scanning calorimetry (DSC) thermograms, thermogravimetric analysis (TGA) profiles, and dynamic vapor sorption profiles (DVS). As is well-known in the art, the graphical data potentially provides additional technical information to further define the respective solid state form which can not necessarily be described by reference to numerical values or peak positions alone. Thus, the term “substantially as shown in” when referring to graphical data in a Figure herein means a pattern that is not necessarily identical to those depicted herein, but that falls within the limits of experimental error or deviations, when considered by one of ordinary skill in the art. The skilled person would readily be able to compare the graphical data in the Figures herein with graphical data generated for an unknown crystal form and confirm whether the two sets of graphical data are characterizing the same crystal form or two different crystal forms.

The terms “polymorph” or “crystalline form” refer to distinct crystal arrangements of the same chemical composition. The term “form” includes polymorphs, crystalline forms, and non-crystalline (amorphous) solids.

A solid, crystalline form may be referred to herein as “polymorphically pure” or as “substantially free of any other form.” As used herein in this context, the expression “substantially free of any other forms” will be understood to mean that the solid form contains about 20% or less, about 10% or less, about 5% or less, about 2% or less, about 1% or less, or 0% of any other forms of the subject compound as measured, for example, by XRPD.

In some embodiments of the disclosed methods, the administering is oral, peroral, subcutaneous, intramuscular, intravenous, transmucosal, sublingual, buccal, transdermal, intraintestinal, rectal, or intrapulmonary.

As used herein, the term “orally co-administering” refers to simultaneous administration, or sequential administration in such a manner that the fospropofol, or a pharmaceutically acceptable salt thereof, and the pharmaceutically acceptable acid are present in the subject's stomach at the same time.

The term “migraine,” as used herein, refers to a chronic neurovascular disorder characterized by recurrent attacks of often severe headache (“migraine attacks”), typically accompanied by nausea and sensitivity to light and/or sound. Migraine is a clinical diagnosis, criteria for which would be known and understood by those practicing in the treatment of migraine, and would include, for example, the criteria proposed by the International Headache Society (IHS). See http://ihs-classification.org/en/.

“Migraine with aura” is migraine characterized by focal neurological symptoms that typically precede, or sometimes accompany, the headache.

“Migraine without aura” is migraine characterized by the absence of focal neurological symptoms that typically precede, or sometimes accompany, the headache.

“Refractory migraine,” as used herein, refers to migraine that fails to respond to pharmacologic treatment. Failure to respond in this regard includes, for example, failure of a pharmacological treatment to eliminate migraine pain, as well as failure of a pharmacological treatment to reduce severe or moderate migraine pain to mild migraine pain. Refractory migraine may fail to respond to one or more types of pharmacologic treatment, for example, acute pharmacologic treatment. Examples of pharmacologic treatments to which refractory migraine may fail to respond include nonsteroidal anti-inflammatory agents (e.g. ibuprofen, naproxen sodium diclofenac, ketorolac), CGRP inhibitors (e.g., gepants rimegepant, ubrogepant and atogepant; anti-CGRP or anti-CGRP receptor antibodies), dihydroergatime mesylate, and triptans (e.g., sumatriptan (Imitrex), rizatriptan (Maxalt), almotriptan (Axert), naratriptan (Amerge), zolmitriptan (Zomig), frovatriptan (Frova) and eletriptan (Relpax)).

The term “effective amount” or “therapeutically effective amount”, as used herein, refers to an amount sufficient to reduce or eliminate the signs or symptoms of the condition for which fospropofol is being administered.

The effective amount may be the amount given in a single dose, or may be the cumulative amount given in multiple doses.

The term “most bothersome symptom” (or “MBS”), is the migraine symptom, other than pain, that is most bothersome to the patient. Examples of MBS include nausea, photophobia, and phonophobia.

The term “bothersome symptom” is a migraine symptom, other than pain, that is bothersome to the patient. Examples include nausea, photophobia, and phonophobia.

As used herein, “photophobia” refers to sensitivity to light.

As used herein, “phonophobia” refers to sensitivity to sound.

As used herein, “hypotention” refers to a fall from baseline blood pressure greater than 20 mm Hg systolic or 20 mm diastolic.

As used herein, the terms “pain relief,” “relief from pain,” “relief from headache pain,” or “headache pain relief” refer to either eliminating pain or reducing severe or moderate pain to mild pain.

As used herein, the term “within” as used to characterize a period of time (e.g., “within 2 hours”) includes the specified time point as well as any time points prior to the specified time point. For example, “within 2 hours” includes the time point 2 hours, as well as, for example, 15 minutes, 30 minutes, 1 hour, and 1.5 hours.

As used herein, the term “pulsatile release” refers to a release in which the fospropofol is released from the dosage form in two or more portions, with periods of time between subsequent releases in which little or no drug release takes place.propofolpropofol. A pulsatile release dosage form is prepared by, for example, combining an immediate release portion with a delayed release portion; or combining two or more delayed release portions wherein each portion releases drug at a different time following administration. Examples of dosage forms that provide pulsatile release include capsules containing immediate release granules and delayed release granules; bilayer tablets having an immediate release layer and a delayed-release layer.

The term “modified release” as used herein, refers to a dosage form in which the release of drug is modified relative to an immediate release dosage form.

As used herein, the term “extended release dosage form” refers to a dosage form that releases the encompassed fospropofol over an extended period of time.

A “pharmaceutically acceptable excipient” refers to a substance that is non-toxic, biologically tolerable, and otherwise biologically suitable for administration to a subject, such as an inert substance, added to a pharmacological composition or otherwise used as a vehicle, carrier, diluent, or release modifier to facilitate administration of an agent and that is compatible therewith.

The term “dose”, as used herein, refers to an amount of fospropofol, a pharmaceutically acceptable salt of fospropofol, or mixtures thereof, administered to the patient at a point in time. A dose may be administered in a single dosage form (e.g., tablet, capsule, etc.), or in multiple dosage forms. For example, an 800 mg “dose” of fospropofol may be administered in a single 800 mg tablet, in two 400 mg tablets, or in a 600 mg tablet and a 200 mg capsule. In other aspects, a dose may be administered via a modified release dosage form that releases a first amount of fospropofol, a pharmaceutically acceptable salt of fospropofol, or mixtures thereof, to the patient at a point or period in time, followed by a second amount fospropofol, a pharmaceutically acceptable salt of fospropofol, or mixtures thereof, to the patient at another point or period in time.

EXAMPLES Example A1

A randomized, double blind, placebo-controlled, ascending single-dose, safety-tolerability, pharmacokinetic, and efficacy study of PO fospropofol administered to young healthy male and female volunteers for the acute treatment of moderate or severe migraine headache is conducted as follows.

This study will assess the safety-tolerability, pharmacokinetics, and efficacy (pain relief) of ascending single oral (PO) doses of fospropofol administered to healthy young male and female volunteers for the acute treatment of moderate or severe migraine headache.

The study will also assess the efficacy for relief of associated symptoms (nausea, photophobia, phonophobia) of ascending single oral doses of fospropofol administered to healthy young male and female volunteers for the acute treatment of moderate to severe migraine headache.

Inclusion criteria: Male and female volunteers, age 18-65 years inclusive with an established diagnosis of migraine, with or without aura, according to IRS criteria. The age at the time of initial migraine diagnosis<50 yo, and the time since initial diagnosis of migraine>one year. The estimated frequency of migraine episodes classified as moderate or severe is at least one per month on average over the past year. Subjects with coexisting headache other than migraine are eligible provided that these headaches are distinguishable from the subject's migraine headaches. No relevant contraindication to use of fospropofol or propofol according to FDA approved labeling. Concomitant medications intended to reduce the frequency of migraine are permitted provided that the dose is stable for at least 3 months prior to enrolment and estimated headache frequency meets the criterion above. If concomitant medications intended to reduce the frequency of migraine are discontinued prior to the study, these medications must be discontinued at least one month prior to enrolment. Patients will also have an absence of any clinically significant medical condition that, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study.

Exclusion criteria: Subjects with any medical condition (e.g., sleep apnea) which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from the administration of study drug. Subjects with a contraindication to use of fospropofol or propofol according to FDA approved labeling. Subjects with any medical condition, which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study. Subjects who require concomitant medications, the use of which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study. Subjects unable or unwilling to provide informed consent. Women of childbearing potential must be on adequate, reliable contraception.

Five separate cohorts of 12 subjects are scheduled to receive ascending single PO doses of fospropofol or placebo under double-blind conditions in five stages corresponding to planned doses of 200 mg, 600 mg, 800 mg, 1000 mg, and 1200 mg. Each cohort will participate in each stage (10 to receive fospropofol and 2 to receive placebo). Assuming the completion of five stages, the total number of subjects participating is 60 (50 to receive fospropofol and 10 to receive placebo).

Two subjects within each cohort are randomly assigned to receive placebo.

Following each stage, the decision whether to progress to the next dose is based on a review of safety, tolerability and pharmacokinetic (PK) data from the preceding stage by the Safety Committee, as described below.

The Safety Committee may approve dose escalation according to the dose levels planned in the protocol, may recommend against dose escalation, may recommend study of an intermediate dose level other than the dose levels planned in the protocol, or may recommend that additional data be gathered at a dose level already studied.

Treatment A—200 mg Fospropofol administered as 1 capsule containing 200 mg fospropofol

Treatment B—600 mg Fospropofol administered as 3 capsules, each containing 200 mg fospropofol

Treatment C—800 mg Fospropofol administered as 4 capsules, each containing 200 mg fospropofol

Treatment D—1000 mg Fospropofol administered as 5 capsules, each containing 200 mg fospropofol

Treatment E—1200 mg Fospropofol administered as 5 capsules, each containing 200 mg fospropofol

Treatment P—Placebo capsule—matching the appearance of the capsule containing 200 mg of fospropofol; Number of placebo capsules to depend on the dosing stage.

Within each separate cohort of 12 subjects, 10 subjects will receive single ascending PO doses of fospropofol at the dose levels below. Two of the 12 subjects in each cohort will be randomly assumed to receive placebo.

Level Planned dose (mg) 1 200 2 600 3 800 4 1000 5 1200

1200 mg is the maximum planned dose. The dose escalation will be stopped if there is any evidence of tolerability issues. Thus, the highest dose administered may be lower than 1200 mg.

Following completion of each dose level, PK data collected until 9 hours post-dose, and safety, tolerability data will be evaluated by a Safety Committee before proceeding to the next dose. Depending on safety and tolerability as well as available PK data, the dose escalation may be modified such that intermediate dose levels are administered.

The Safety Committee will include at least the Qualified Investigator (QI), one medically qualified Sponsor representative, and an independent third-party physician. Adjustments to the currently outlined doses and/or dosing regimen may be implemented by the Safety Committee, but the dose to be administered at a given dose level will not exceed the dose currently outlined in the protocol.

Minutes of the safety review committee meeting will be prepared and signed by all voting participants. The minutes of the safety review committee meetings (including the decisions to escalate the dose, determination of the next dose level, increase in the safety monitoring, rationale for the decisions and supportive data) will be shared with the Independent ethics committee(s) [IEC(s)]/Institutional review board(s) [IRB(s)] overseeing the concerned study part.

The subject's blood will be sampled pre-dose (within 15 min of dosing) and post-dose: 5, 10, 20, 30, 45, 90 minutes and 2, 4, 6, and 9 hours post-dose. Plasma samples will be assayed for fospropofol and propofol using validated analytical method(s) according to the principles of Good Laboratory Practice.

The following parameters will be calculated with fospropofol and propofol plasma concentrations: AUC₀-30 min, AUC₀-2 h, AUC₀-t, AUC0-inf, Cmax, Residual area, Tmax, T½ el, Kel, Cl/F, Vd/F, and Vd/F/kg.

Subject's will assess headache pain utilizing a 4-point Likert Scale to be assessed at baseline (within 15 min of dosing), and post-dose at 15 min, 30 min, 1 h, 1.5 h, 2 h, 4 h, 6 h, 8 h, 10 h (in clinic) and following discharge (by diary) at 24 h and 48 h post-dosing. Subjects will be asked to record by patient diary any recurrence or worsening of headache pain, and time of onset or worsening. (Note that a qualifying headache must be of at least moderate severity.)

Subjects will assess presence/absence of the most bothersome associated symptom for the presenting headache at baseline (within 15 min of dosing), and post-dose at 15 min, 30 min, 1 h, 1.5 h, 2 h, 4 h, 6 h, 8 h, 10 h (in clinic) and following discharge (by diary) at 24 h and 48 h post-dosing. Subjects will be asked to record by patient diary any recurrence or worsening of the most bothersome symptom, and time of onset or worsening.

Subject's will assess the presence/absence of nausea/vomiting, photophobia, and/or phonophobia at baseline (within 15 min of dosing), and post-dose at 15 min, 30 min, 1 h, 1.5 h, 2 h, 4 h, 6 h, 8 h, 10 h (in clinic) and following discharge (by diary) at 12 h, 24 h and 48 h post-dosing. Subjects will be asked to record by patient diary any recurrence or worsening of the most bothersome symptom, and time of onset or worsening.

Subjects will be instructed to report any adverse events directly to the investigators or clinic staff. Subjects will be instructed to record in the patient diary any adverse events emerging following discharge. All subjects will have telephone access to the investigator or investigator staff to report any urgent concerns in the course of the study.

In order to detect the possible emergence of any clinically significant cardiac arrhythmia or other abnormality cardiac telemetry will be monitored from pre-dose until 10 hours post-dose. Volunteers with any clinically significant ECG abnormality at baseline (pre-dose) will be excluded.

Blood pressure (BP), heart rate (HR), respiratory rate (RR), and pulse oximetry will be recorded within 15 min pre-dose and at approximately 30 min, and 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after dosing.

Modified Observer's Assessment of Alertness/Sedation (OAA/S) score within 15 min pre-dose and at approximately 15 min, 30 min, and 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, and 10 hours after dosing will be assessed.

Hematology, biochemistry, and urinalysis will be assessed at screening and end of study participation.

Alcohol breath test, urine cotinine determination, and urine drug screen will be assessed at check-in.

A physical examination will be conducted at screening and end of study. An abbreviated physical exam will be conducted at clinic check-in.

Subjects will be monitored throughout the study by clinic staff for adverse events. A physician will be on site for each drug administration and until 10 hours post-dose, and available on call for the remainder of the study.

This study will demonstrate that fospropofol, administered per orally, is safe and effective in treating migraine.

Subjects with coexisting headache other than migraine are eligible provided that these headaches are distinguishable from the subject's migraine headaches. No relevant contraindication to use of fospropofol or propofol according to FDA approved labeling. Concomitant medications intended to reduce the frequency of migraine are permitted provided that the dose is stable for at least 3 months prior to enrolment and estimated headache frequency meets the criterion above. If concomitant medications intended to reduce the frequency of migraine are discontinued prior to the study, these medications must be discontinued at least one month prior to enrolment. Patients will also have an absence of any clinically significant medical condition that, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study.

Exclusion criteria: Subjects with any medical condition (e.g., sleep apnea) which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from the administration of study drug. Subjects with a contraindication to use of fospropofol or propofol according to FDA approved labeling. Subjects with any medical condition, which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study. Subjects who require concomitant medications, the use of which, in the opinion of the investigator or the Sponsor, may be potentially associated with an increased risk from participation in the study. Subjects unable or unwilling to provide informed consent. Women of childbearing potential must be on adequate, reliable contraception.

A separate cohort of 36 subjects will be randomized to receive one of 3 regimens (N=12/group) under double-blind conditions, each regimen comprising a single administration of one of the dosage forms of Example 5, 6, or 7. Double-blinding will be preserved by administering an appropriate number of active and placebo capsules for the second dose.

The subject's blood will be sampled pre-dose (within 15 min of dosing) and post-dose: 5, 10, 20, 30, 45, 90 minutes and 2, 4, 6, and 9 hours post-dose. Plasma samples will be assayed for fospropofol and propofol using validated analytical method(s) according to the principles of Good Laboratory Practice.

Example A15—Animal Studies Study No. 15-1

The purpose of Study No. 15-1 (non-GLP) was to determine the maximum tolerated dose (MTD) of fospropofol when administered by oral gavage to Sprague-Dawley rats (Phase 1) and to evaluate the potential toxicity of fospropofol in Sprague-Dawley rats when administered once daily by oral gavage for 7 days (Phase 2). In addition, the toxicokinetic (TK) profiles of fospropofol and propofol were determined. Oral gavage administration of fospropofol disodium to Sprague-Dawley rats at single fospropofol dose levels up to 300 mg/kg or once daily for 7 consecutive days at fospropofol dose levels of 150 and 250 mg/kg/day was well tolerated at all doses. Although one 150 mg/kg/day TK female was found dead on Day 7 at approximately 30 minutes postdose, the cause of death was considered related to the pharmacodynamic effects of fospropofol. Based on these results, the MTD was considered to be 250 mg/kg/day (1500 mg/m²/day).

Study No. 15-2

The purpose of Study No. 15-2 (non-GLP) was to determine the MTD of fospropofol when administered by oral gavage to Beagle dogs (Phase 1) and to evaluate the potential toxicity of fospropofol in Beagle dogs when administered once daily by oral gavage for 7 days (Phase 2), as well as to determine the TK profiles of fospropofol and propofol. Administration of fospropofol disodium by oral gavage to Beagle dogs at single fospropofol dose levels up to 120 mg/kg or at fospropofol dose levels of 120 and 160 mg/kg/day once daily for 7 days was tolerated at all doses with no mortality or adverse findings. Based on these results, the MTD was considered to be 160 mg/kg/day (3200 mg/m²/day).

Study No. 15-3

The purpose of Study No. 15-3 (GLP) was to determine the potential toxicity of fospropofol in Sprague-Dawley rats when administered once daily by oral gavage for 14 days Administration of fospropofol disodium by once daily oral gavage to Sprague-Dawley rats at fospropofol dose levels of 0, 50, 100, and 250 mg/kg/day for 14 consecutive days resulted in treatment-related mortalities at 250 mg/kg/day. The cause of death for the three 250 mg/kg/day group main study females found dead could not be determined, but was considered related to the pharmacodynamic effects of fospropofol, based on the time of death relative to the time of dose administration, and the clinical signs recorded before death. Clinical observations during the dosing period for these animals included labored breathing, prostrate, splayed hindlimbs, uncoordinated movement, decreased activity, and eyes closed. There were no treatment-related gross observations or microscopic findings in any of these animals. Based on these results, the NOAEL was determined to be 100 mg/kg/day (600 mg/m²/day). Systemic exposure to fospropofol and propofol appeared to be dependent on sex, with greater exposure in females. The toxicokinetic results are presented in the tables below.

Fospropofol Exposure

Following daily oral gavage administration of fospropofol disodium to males and females at fospropofol doses of 50, 100, and 250 mg/kg/day, peak plasma concentrations (C_(max)) and area under the curve (AUC) through 6 hours after dosing (AUC_(0-6 hr)) increased for fospropofol on Day 1 and Day 14 with increasing dose in a greater than dose-proportional manner. Systemic exposure (AUC_(0-6 hr) values) to fospropofol did not appear to change following repeated administration of fospropofol disodium to male and female rats) Table 15-1.

Propofol Exposure

Following daily oral gavage administration of fospropofol disodium to males and females, C_(max) and AUC_(0-6 hr) values for propofol increased with increasing fospropofol dose in an approximately dose-proportional manner on Days 1 and 14. Systemic exposure (AUC_(0-6 hr) values) to propofol did not appear to change following repeated administration of fospropofol disodium to male rats, but exposure appeared to increase following repeated administration of fospropofol disodium to female rats (Table 15-2).

Study No. 15-4

The purpose of Study No. 15-4 (GLP) was to determine the potential toxicity of fospropofol in Beagle dogs when administered once daily by oral gavage for 14 days. Administration of fospropofol disodium once daily by oral gavage to Beagle dogs at fospropofol dose levels of 0, 50, 100, and 160 mg/kg/day for 14 consecutive days was well tolerated at all dose levels with no adverse findings. Because the treatment-related clinical observations (consistent with the expected transient sedative actions of fospropofol) and effects on hematology and clinical chemistry parameters were considered nonadverse, the NOAEL was determined to be 160 mg/kg/day (3200 mg/m²/day). The toxicokinetic results are presented in the tables below.

Fospropofol Exposure

Following daily oral gavage administration of fospropofol disodium, plasma concentrations of fospropofol increased rapidly. The T_(max) ranged from 0.0833 to 1 hour after dosing (Table 15-3). No consistent changes in T_(max) with time, dose, or sex were observed. Where accurate determination was possible, apparent individual terminal half-lives varied from 0.3 to 0.6 hours in males and females.

In both males and females, fospropofol C_(max) and AUC_(0-6 hr) increased in a manner that was less than dose proportional on Days 1 and 14, except in females on Day 14, where the increase was dose proportional. Among males, C_(max) and AUC_(0-6 hr) did not increase with repeat dosing, whereas among females AUC_(0-6 hr) appeared to increase with repeat dosing at the 100-mg/kg and the 160-mg/kg propofol dose levels (Table 15-3). After single and repeated oral gavage administration at propofol dose levels of 50, 100, and 160 mg/kg/day for 14 days, no clear sex differences were noted for C_(max) or AUC_(0-6 h); however, at 100 and 160 mg/kg/day on Day 14, a slight trend toward a lower exposure was observed in males compared to females.

Blood (plasma) was collected from separate cohorts of 4 animals per sex per treatment group at predose and approximately 0.083, 0.25, 0.5, 1, 3, and 6 hours postdose.

Propofol Exposure

The metabolite propofol was formed with a T_(max) of 0.0833 to 1 hour in most groups after dosing (Table 15-4). No consistent changes in T_(max) with time, dose, or sex were observed. Where accurate determination was possible, apparent individual terminal half-lives varied from 0.8 to 1.8 hours in males and from 0.5 to 1.3 hours in females.

Following daily oral gavage administration of fospropofol disodium, propofol C_(max) and AUC_(0-6 hr) appeared to increase in both sexes in a manner that was dose proportional on Day 1 and more than dose proportional on Day 14. At the 160-mg/kg propofol dose, after 14 days of dosing, C_(max) increased about 7-fold in males and 3-fold in females compared with Day 1; AUC_(0-6 hr) after 14 days of dosing compared with Day 1 increased over 2-fold in males and over 5-fold in females (Table 15-4). It should be noted that these observations should be interpreted with caution due to relatively high variability of TK parameters among animals within the same dose group.

Summary of Nonclinical Toxicology of Fospropofol Disodium

Pivotal GLP 14-day repeat-dose toxicity studies with 7-day recovery periods were conducted in Sprague-Dawley rats (Study No. 15-3) and Beagle dogs (Study No. 15-4). In the rats, daily oral administration of fospropofol disodium for 14 days at fospropofol dose levels of 0, 50, 100, and 250 mg/kg/day (0, 300, 600, and 1500 mg/m²/day, respectively) resulted in 4 mortalities at the high dose level. The cause of death for these animals was considered to be related to the known pharmacodynamic effects of high doses of fospropofol, based on the time of death relative to the time of dose administration, and the clinical signs recorded before death which included: labored breathing, prostrate, splayed hindlimbs, uncoordinated movement, decreased activity, and eyes closed. Other treatment-related effects included reduced body weight gain at 250 mg/kg/day, and a transient increase in prothrombin time at 250 mg/kg/day. There were no treatment-related histopathology findings in any tissues, including all GIT-related tissues that were evaluated, indicating that there were no local toxicities associated with orally administered fospropofol disodium at fospropofol dose levels up to 250 mg/kg/day (the MTD established in this species). The NOAEL was determined to be 100 mg/kg/day (600 mg/m²/day) in male and female Sprague-Dawley rats.

In Beagle dogs, daily oral administration of fospropofol disodium for 14 days at fospropofol dose levels of 0, 50, 100, and 160 mg/kg/day (0, 1000, 2000, and 3200 mg/m²/day, respectively) resulted in no mortalities. As in the rat, CNS-related clinical signs were observed which were consistent with the established pharmacodynamic effects of fospropofol. There were no toxicologically significant changes in body weights, cardiovascular evaluations (ECGs, including QTc), ophthalmology, clinical pathology (hematology, coagulation, clinical chemistry, and urinalysis), and absolute or relative organ weights. No gross necropsy findings were observed at main or recovery sacrifices, and there were no treatment-related histopathological findings in any tissues, including all GIT-related tissues. As for the rat, the absence of histopathology findings in the GIT indicated that there were no local toxicities associated with orally administered fospropofol disodium at fospropofol dose levels up to 160 mg/kg/day in the dog (the MTD established in this species). The NOAEL was determined to be 160 mg/kg/day (3200 mg/m²/d) in male and female Beagle dogs.

Overall, no new treatment-related adverse findings were observed in the oral fospropofol toxicology studies that would limit the use of fospropofol disodium in healthy volunteer or migraine patient populations.

Example A16 Part 1: PK of Single Ascending Doses of Fospropofol Disodium (200 to 2000 mg)

Part 1 of Study A16 was a double-blind, randomized, placebo-controlled study to investigate the safety-tolerability and PK of oral administration of single ascending doses of fospropofol disodium to healthy adult male and female volunteers.

Subjects were healthy adults (age 18-55 years inclusive, BMI 18-29.9 kg/m²). Separate cohorts of 12 subjects each were randomized to receive fospropofol disodium at doses of 200, 400, 800, 1000, 1200, 1600, or 2000 mg (n=10 per cohort) or matching placebo (n=2 per cohort).

Subjects were admitted to the clinical unit for an overnight fast (Day −1), administered study drug on Day 1, and remained in the clinical unit until Day 2.

Fospropofol disodium was formulated as powder in an HPMC capsule, each capsule containing 200 mg of fospropofol disodium (weight adjusted for water content). Placebo was administered as an appropriate number of matching capsules.

Blood samples were collected for analysis of fospropofol and propofol at predose and at 5, 10, 20, 30, 45 minutes, and 1, 1.5, 2, 4, 6 and 9 hours postdose (Cohorts 1-2). Based on PK results from the early cohorts, sampling times were optimized beginning with Cohort 3 (800 mg) to predose, 5, 10, 15, 20, 25, 30, 37, and 45, minutes and 1, 2, 4, 6, and 9 hours after dosing.

The following pharmacokinetic parameters were determined for fospropofol and propofol from plasma: area under the curve from time of dosing to last measured time point (AUC_(0-t)), area under the curve from time of dosing extrapolated to infinity (AUC_(0-inf)), residual area, maximum plasma concentration (C_(max)), time to maximum concentration (T_(max)), t_(1/2), apparent clearance (Cl/F), and apparent volume of distribution (V_(d)/F).

Pharmacokinetic parameters are summarized in Table 16-1 and Table 16-2. Mean concentration vs. time plots for fospropofol and propofol by cohort are shown in FIG. 1.

Table 16-1 and FIG. 1 indicate that the median T_(max) for fospropofol occurred at approximately 20 minutes, with fospropofol concentrations falling substantially (to less than 10% of C_(max)) by 2 hours after dosing.

Table 16-2 and FIG. 1 indicate that the median T_(max) for propofol was dose-related, ranging from 30 minutes after the 200-mg dose to 45 minutes after doses of 1600 or 2000 mg, with propofol concentrations falling substantially (to less than 25% of C_(max)) by 4 hours after dosing.

Dose proportionality assessment using the power model indicated that the PK parameters for fospropofol (AUC_(0-2 hr), AUC_(0-T), AUC_(0-∞), and C_(max)) were dose proportional over the dose range from 200 mg to 2000 mg.

The PK parameters for propofol (AUC_(0-2 h) and C_(max)) were dose proportional over the dose range from 200 mg to 2000 mg, whereas AUC_(0-T) and AUC_(0-∞) values for propofol increased with dose in a slightly greater than dose-proportional manner. Based on the power model, C_(max) and AUC_(0-∞) values for propofol were dose proportional over the dose range from 200 mg to 1200 mg, whereas AUC_(0-T values increased with dose in a slightly greater than dose-proportional manner.)

Within each cohort, the coefficient of variation (CV) around the mean C_(max) for propofol was greater than the CV around the mean C_(max) for fospropofol. The CV around the mean C_(max) for propofol ranged from 30% to 99% across the cohorts. Contributing to the wider variability in propofol C_(max) was the presence of occasional “outlier” values for the propofol C_(max) that were more than 2 standard deviations above the mean for the respective dose cohort (Table 16-3).

Table 16-3 illustrates that the highest observed C_(max) values within the 200, 400, 800, and 1000 mg cohorts were greater than 2 standard deviations above the mean for that cohort. The highest observed C_(max) values in the 200, 400, 800, and 1000 mg cohorts were more than 2 times the mean C_(max) value for the respective cohort. In the 800-mg cohort, the highest observed C_(max) value was 1352.75 ng/mL, a value approximately 3.7-fold higher than mean value of C_(max) (362 ng/mL) for the 800 mg cohort. Analyses to explore the role of subject-related factors potentially predictive of unusually high C_(max) values, e.g., weight, BMI, sex, age, serum alkaline phosphatase did not identify any predictive factor.

The preliminary PK data from Study A16, Part 1, indicated that exposure to propofol (both C_(max) and AUC) after oral administration of fospropofol disodium was approximately dose proportional over the dose range of 200 to 2000 mg. Within each dose cohort, the intersubject variability for propofol exposure was greater than for fospropofol. Most of the dosing cohorts were characterized by the observation of 1 subject with unusually high propofol exposure. Analyses to explore the role of subject-related factors potentially predictive of unusually high C_(max) values, e.g., weight, BMI, sex, age, serum alkaline phosphatase, did not identify any predictive factor.

Part 2: PK of a Single Dose of 1200 mg Fospropofol Disodium Following a High-Fat Meal

Part 2 of Study A16 was a double-blind, placebo-controlled, single-dose pilot study to investigate the PK, safety, and tolerability of 1200 mg of fospropofol disodium administered to healthy adult men and women following a high-fat meal.

Subjects were healthy adults (age 18-55 years inclusive, BMI 18-29.9 kg/m²). A separate cohort of 15 subjects was randomly assigned to receive a single oral dose of either fospropofol disodium (n=12) or matching placebo (n=3) within 30 minutes (+1 minute) after the start of a standardized high-fat meal.

Subjects were admitted to the clinical unit for an overnight fast (Day −1), administered study drug on Day 1 within 30 minutes of the start a standardized high-fat meal, and remained in the clinical unit until Day 2.

Fospropofol disodium was formulated as powder in 6 HPMC capsules, each capsule containing 200 mg of fospropofol disodium (weight adjusted for water content). Placebo was administered as 6 matching capsules.

Blood samples were collected for analysis of fospropofol and propofol at predose, 5, 10, 15, 20, 25, 30, 37, and 45, minutes and 1, 2, 4, 6, and 9 hours after dosing.

The following PK parameters were determined for fospropofol and propofol from plasma: area under the curve from time of dosing to last measured time point (AUC_(0-t)), area under the curve from time of dosing extrapolated to infinity (AUC_(0-inf)), residual area, maximum plasma concentration (C_(max)), time to maximum concentration (T_(max)), t_(1/2), apparent clearance (Cl/F), and apparent volume of distribution (V_(d)/F).

PK parameters from the fed cohort (Cohort 8, 1200 mg) are summarized together with the parameters from the fasted cohort that received 1200 mg (Cohort 5, Part 1) in Table 16-9. Mean concentrations are plotted over time for fospropofol and propofol by cohort in FIG. 2.

Compared with subjects in Part 1 who received 1200 mg of fospropofol disodium under fasting conditions, subjects who received 1200 mg of fospropofol disodium following a high-fat meal showed a significant reduction in exposure (Table 16-9). Mean exposure to fospropofol under fed conditions (both C_(max) and AUC) was approximately 24% of the exposure under fasting conditions, with no appreciable effect on T_(max) (median, 0.333 h). For propofol, the mean AUC following a high-fat meal was approximately 40% of the mean AUC observed under fasting conditions, and the mean C_(max) under fed conditions was approximately 19% of the mean C_(max) observed under fasting conditions Administration of fospropofol disodium after a high-fat meal delayed the propofol T_(max) from a median value of 0.617 (range, 0.417-2.00) hours under fasting conditions to a median value of 2.00 (range, 0.500-4.00) hours.

Results of the pilot food-effect study indicate that administration of fospropofol disodium 1200 mg within 30 minutes after the start of a high-fat meal is associated with a significant reduction in exposure to both fospropofol and propofol.

Example A17. Study A17

Open-label study to describe the pharmacokinetics, and safety, tolerability, and relief of pain and associated migraine symptoms (nausea/vomiting, photophobia, phonophobia) following a single oral dose of fospropofol administered to adult women and men experiencing moderate to severe migraine headache.

Study Assessments

A total of 7 blood samples of 6 mL each will be collected for analysis of fospropofol and propofol PK. The PK samples will be collected at the following time points: predose (within 120 minutes before dosing) and postdose at 10, 20, and 40 minutes and 1, 2, and 4 hours after dosing.

The time tolerance window for blood samples collected during the confinement period will be ±1 minute for all samples. Sample collections done outside the predefined time windows will not be considered as protocol deviations since actual postdose sampling times will be used for PK and statistical analyses.

When appropriate, an indwelling i.v. catheter will be used for blood collection to avoid multiple skin punctures. Otherwise, blood samples will be collected by direct venipuncture.

In case of an SAE or early withdrawal, a PK blood draw should be performed if possible, at or near the time the subject reports the SAE or at the time of withdrawal from the study.

Blood samples for safety laboratory assessments will be drawn at screening, clinic check-in, and clinic discharge.

The total blood volume drawn per subject will not exceed a maximum of 200 mL, including screening.

Medical Surveillance and AE Monitoring

A 12-lead ECG will be performed at screening, at clinic check-in (within 120 minutes before dosing) and at clinic check-out. Corrected QT interval (QTc) will be recorded.

Subjects will be permitted to sleep ad lib (in a semi-reclined position) after administration of study drug but are to be awakened for the assessments of headache pain and associated migraine symptoms at 1, 2, and 4 hours after dosing.

The subject's sleep status will be recorded after dosing at 15-minute intervals through hour 4 (assessed as “appears to be sleeping” or “appears to be awake”).

Pulse oximetry will be recorded at screening and continuously monitored on Day 1 from at least 15 minutes prior to dosing until discharge from the clinic. The pulse oximeter is to have an alarm set to give both audible and visual notifications when SpO2 drops to 90% or below. If the alarm signals, the subject should be aroused. Nasal oxygen should be considered if SpO2 remains at 90% or lower after stimulation.

SpO2 values will be recorded from the continuous monitor within 15 minutes before dosing, postdose at approximately the same time points as the sleep status assessments (15-minute intervals), and at clinic check-out, with the subject seated or semi-reclined.

Systolic and diastolic BP (mmHg), HR, and RR will be recorded at screening, on Day 1 within 60 minutes before dosing, at 30-minute intervals until 4 hours after dosing, and at clinic check-out 0. For consistency with time points where they should be performed before PK blood draws, these assessments should take place within 10 minutes before each designated time point. Temperature (as degrees Fahrenheit) will be recorded at screening, on Day 1 within 60 minutes before dosing, and at clinic check-out.

BP, HR, and RR are to be assessed with the subject having been in a seated or semi-reclined position for at least 5 minutes. At clinic check-in, elevations of BP or HR attributable to headache pain or other migraine symptoms may be accepted according to the investigator's judgment.

Level of sedation will be assessed using the MOAA/S score at 4 hours after dosing (within 10 minutes before the 4-hour PK blood draw). Cohen LB. Clinical trial: a dose-response study of fospropofol disodium for moderate sedation during colonoscopy. Aliment Pharmacol Ther 2008; 27:597-608. Chernik D A, Gillings D, Laine H, et al. Validity and reliability of the Observer's Assessment of Alertness/Sedation Scale: study with intravenous midazolam. J Clin Psychopharmacol 1990; 10:244-251.

If the MOAA/S score is below 5 at 4 hours after dosing and/or there is reason for concern, the duration of confinement may be extended, and safety monitoring may continue at the discretion of the investigator.

Safety Laboratory Assessments

Hematology

Hematology samples will be drawn at screening, clinic check-in, and clinic check-out. Hematology will include complete blood count with differential, hemoglobin, and hematocrit.

Serum Chemistry

Serum chemistry samples will be drawn at screening, clinic check-in, and clinic check-out. Serum chemistry assessments will include albumin, alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, calcium, chloride, carbon dioxide/bicarbonate, creatinine, glucose, phosphate, potassium, sodium, total bilirubin, total protein, and blood urea nitrogen (BUN).

Serology

Hepatitis B (HBs Ag), Hepatitis C (HCV) antibody, and HIV antigen and antibody detection will be performed at screening. (Reflex HCV RNA testing will be performed for any positive hepatitis C screening test. If the results of reflex testing are negative, the subject may be deemed eligible for the study.)

Urinalysis

Urine for urinalysis will be collected at screening, clinic check-in, and clinic check-out. Urinalysis will include macroscopic examination, pH, specific gravity, protein, glucose, ketones, bilirubin, occult blood, nitrite, urobilinogen, and leukocytes. Unless otherwise specified, microscopic examination will be performed on abnormal findings according to standard procedure.

Drug, Cotinine, and Alcohol

A urine drug screen (amphetamines, methamphetamines, barbiturates, benzodiazepines, THC, cocaine, opiates, PCP, 3,4-methylenedioxy-methamphetamine (MDMA), methadone), a urine cotinine test, and an alcohol breath test will be performed at screening and at clinic check-in.

Pregnancy Tests

For women, a urine pregnancy test will be performed at screening and at clinic check-in. A serum pregnancy test will be performed at clinic check-out for confirmation.

Physical Examination

A complete physical examination will be performed at screening, and abbreviated physical examinations will be performed at clinic check-in and check-out.

The complete physical examination at the screening visit will assess any physical abnormalities and will include at a minimum, assessments of the following body systems: general appearance, overall status of the head, ears, eyes, nose, throat (HEENT), neck, abdomen, lymph nodes, skin, cardiovascular/heart, pulmonary, musculoskeletal, and neurological (level of alertness [more detailed mental status not required unless indicated], speech, cranial nerves, motor strength and tone, cerebellar, sensory, deep tendon reflexes, and gait). Investigators should pay special attention to clinical signs related to previous serious illnesses.

Height and weight will also be measured and recorded at the screening visit.

The abbreviated physical examination at check-in and check-out will assess general appearance, HEENT, cardiovascular, pulmonary, and neurological status. The neurological examination is to consist of level of alertness and speech. Abbreviated physical examinations may be limited to recording change/no change from prior examinations, plus focused examination by system as directed by any AEs reported by the subject (where applicable) or any spontaneous symptom/complaint reported by the subject at the time of the examination.

Sheehan Suicidality Tracking Scale

The Sheehan Suicidality Tracking Scale (S-STS) is a prospective suicidality rating scale to be completed by the investigator or his/her designate. The scale includes 16 questions that allow a longitudinal evaluation of treatment-emergent suicidal ideation and treatment-emergent suicidal behaviors. Sheehan D V, Alphs L D, Mao L, et al. Comparative Validation of the S-STS, the ISST-Plus, and the C-SSRS for Assessing the Suicidal Thinking and Behavior FDA 2012 Suicidality Categories. Innov Clin Neurosci 2014; 11:32-46. Sheehan D V, Giddens J M, Sheehan I S. Status Update on the Sheehan-Suicidality Tracking Scale (S-STS) 2014. Innov Clin Neurosci 2014; 11:93-140.

The S-STS will be completed on a paper form at the site and will be administered at the screening visit, at clinic check-in, and at the Day 3 follow-up telephone interview. The recall period at the screening administration will encompass the time period beginning 30 days prior to the screening visit; the recall period at clinic check-in will be the time period since the screening visit; the recall period for completing the S-STS at the Day 3 telephone interview will be the time period since clinic check-in. The total score plus the subject's response to each item will be recorded.

For each administration of the S-STS, the investigator will immediately evaluate a subject with any response greater than zero to determine if that subject is at risk of self-harm or suicide. If this is the case, the investigator must take appropriate measures to ensure the subject's safety and arrange for an appropriate mental health evaluation.

Any subject with a response greater than zero to any question at screening must be excluded.

At clinic check-in, any subject with a response greater than zero to any question other than Question 2 must be discontinued from the study and the event recorded as an AE, not treatment-emergent. Subjects with a response of 1 (“a little”) to Question 2 will be discontinued at the discretion of the investigator. Subjects with a response greater than 1 on Question 2 will be discontinued.

In case of any response greater than zero at the Day 3 telephone interview, the investigator will immediately evaluate that subject to determine if that subject is at risk of self-harm or suicide. If this is the case the investigator will take appropriate measures to ensure the subject's safety and arrange for an appropriate mental health evaluation. The event will be recorded as a treatment-emergent AE and reported to Syneos Health Safety and Pharmacovigilance within 24 hours.

Measures of Clinical Course (Exploratory Evaluations)

Headache pain and associated migraine symptoms (nausea/vomiting, photophobia, and phonophobia) will be recorded as migraine-related events.

Headache pain will be rated on a 4-point Likert scale (0=none, 1=mild, 2=moderate, 3=severe). Associated migraine symptoms (nausea/vomiting, photophobia, and phonophobia) will be classified as either present or absent.

Migraine-related events observed during the clinic stay will be recorded starting at the (clock) time of the 10-minute predose migraine evaluation and will be updated at the protocol-specified migraine assessment times (1 hour, 2 hours, 4 hours after dosing, and at clinic check-out.

The course of any migraine-related events that are ongoing at clinic discharge will be followed up at the Day 2 (between 24 and 32 hours after dosing) and Day 3 (between 48 and 56 hours after dosing) telephone interviews. Any migraine-related event that is newly emergent after clinic discharge will be recorded and followed up until the Day 3 telephone interview. The time course of migraine-related events after discharge from the clinic will be based on the subject's best recollection of events as reported at the telephone interviews.

The assessment of migraine-related events during the clinic stay and at the follow-up telephone interviews should begin with a non-leading question (without specific prompting) such as, “How are you doing?” Any AEs reported by the subject should be recorded.

Structured interview questions are used for assessing headache pain and migraine-related symptoms at screening, headache onset, clinic check-in, within 10 minutes before dosing, postdose, and at the follow-up telephone interviews

Statistical Considerations

Safety and Tolerability

Safety and tolerability data will be reported using descriptive statistics. Summary statistics for TEAEs will be reported. Changes from baseline values in vital signs, ECG, and clinical laboratory parameters will be reported.

PK

Interim bioanalysis and PK analyses for fospropofol and propofol are to be performed after approximately 10 subjects have been completed, again after approximately 30 subjects are completed, and may be performed at other intervals as well.

Summary statistics will be used to describe the PK profile of both fospropofol and propofol. Summary statistics will include at minimum arithmetic and geometric means for AUC0-t, AUC0-inf, and Cmax. Tmax will be characterized by median and range.

Exploratory Analyses

Clinical Course

Summary statistics of the subject's assessment of headache pain (on the Likert scale) at clinic check-in, within 10 minutes predose (baseline), 1, 2, and 4 hours postdose, at clinic discharge, and at follow-up on Days 2 and 3 will be reported. Summary statistics of headache recurrence or worsening will also be reported.

Summary statistics of the subject's assessment of the most bothersome symptom (presence or absence) at 1, 2, and 4 hours postdose, at clinic discharge, and at follow-up on Days 2 and 3 will be reported. Summary statistics of recurrence or worsening of the most bothersome symptom will also be reported.

Summary statistics of the subject's assessment of migraine-associated symptoms other than the most bothersome symptom as applicable (presence or absence) at 1, 2, and 4 hours postdose, at clinic discharge, and at follow-up on Days 2 and 3 will be reported. Summary statistics regarding recurrence or worsening of migraine-associated symptoms will also be reported.

Summary statistics reported will include but not be limited to (1) proportion of subjects reporting no headache pain at 2 hours; (2) proportion of subjects reporting the absence of most bothersome symptom at 2 hours; (3) proportion of subjects reporting improvement in pain (change from severe/moderate to mild/absent) at 2 hours; and (4) durability of responses over 24 and 48 hours regarding freedom from headache pain, absence of most bothersome symptom, and improvement in headache pain. All analyses will be exploratory.

Influence of Covariates; PK-PD Relationships

Exploratory analyses will be performed in an effort to characterize the influence of covariates on PK (e.g., relationship between plasma propofol concentrations and gender, age, weight, and BMI) and to characterize PK-PD relationships (e.g., relationship between plasma propofol concentrations and AEs). Exploratory analyses will also be performed in an effort to characterize the relationship between plasma propofol concentration (e.g., Cmax and or partial AUC) and the clinical course of migraine symptoms.

Analytical Methodology

Samples will be transported to the bioanalytical facility packed on sufficient dry ice to keep them frozen for at least 72 hours.

Fospropofol and propofol concentrations will be analyzed in plasma samples using a validated method.

The bioanalytical work in support to the study will be conducted in compliance with GCP using the SOPs in place in the bioanalytical laboratory of Syneos Health. Those SOPs were written in accordance with the current regulations and guidelines in place for industry, including guidances on Bioanalytical Method Validation, Good Laboratory Practice (GLP) for Nonclinical Laboratory Studies, and Good Clinical Practice (GCP) International Conference on Harmonisation (ICH) E6(R2).

Systemic Exposure to Propofol after Administration of Fospropofol Disodium to Subjects with Migraine is Inversely Related to Time to Treatment

Fospropofol Disodium, 800 mg, was administered orally under medical supervision to 12 adult subjects in the course of a migraine episode (within 4 hours of the reported onset of migraine symptoms). Subjects reported time of onset of migraine symptoms and the time interval between onset of symptoms and treatment with Fospropofol Disodium (time-to-treatment) was recorded. Plasma concentrations of fospropofol and propofol were measured predose and at intervals until 4 hours after dosing. The potential influence of a variety of covariates on systemic exposure (maximal plasma concentration [Cmax] and area under the plasma concentration curve at 1, 2, and 4 hours [AUC₁, AUC₂, AUC₄]) for both fospropofol and propofol was examined. One of 12 migraine subjects who exhibited negligible plasma concentrations for both fospropofol and propofol was excluded from analysis. Values for Cmax and AUCs were log-transformed. Time to treatment among the migraine subjects ranged from 115 to 230 minutes.

Among the 11 migraine subjects in the analysis (all female), there was a statistically significant inverse association between time-to-treatment and log propofol Cmax (p=0.007), log propofol AUC₁ (p=0.004), log propofol AUC₂ (p=0.009), and log propofol AUC4 [FIGS. 18, 20, 22, 24]. A similar trend (not statistically significant) toward an inverse association between time-to-treatment and fospropofol exposure was observed for log fospropofol Cmax (p=0.067) and log fospropofol AUC₁ (p=0.98) [FIGS. 17 and 19]. The statistically significant inverse association between propofol exposure and time-to-treatment was unchanged after adjustment for other covariates including age, weight, BMI, and reported time since last meal. Time-to-treatment accounted for ˜57%, 63%, 55%, and 40% of the variability in propofol log Cmax, propofol log AUC₁, propofol log AUC₂, and propofol log AUC₄, respectively [FIGS. 18, 20, 22, 24]. Beta coefficients from the linear regressions [FIGS. 18, 20, 22, 24] indicate that over the observed time-to-treatment interval, geometric mean [GM] propofol C_(max) decreased by 1.45% per minute of delay in time-to-treatment (58.5% per hour); GM propofol AUC₁ decreased by 1.84% per minute (67.2% per hour); GM propofol AUC₂ decreased by 1.62% per minute (62.5% per hour); and GM propofol AUC₄ decreased by 1.08% per minute (47.7% per hour).

To explore whether the bioavailability of propofol relative to fospropofol was inversely associated with time to treatment, the log of the ratio of AUC₁ propofol to AUC₁ fospropofol and the log of the ratio of AUC₂ propofol to AUC₂ fospropofol were used as approximate indicators of the relative bioavailability at 1 and 2 hours after dosing [FIGS. 25 and 26]. There was a trend (not statistically significant) toward an inverse association of time-to-treatment with the log of the ratio of AUC₁ propofol to AUC₁ fospropofol (p=0.141) and the log of the ratio of AUC₂ propofol to AUC₂ fospropofol (p=0.157) [FIGS. 25 and 26]. A comparison of the log of the ratio of AUC₁ propofol to AUC₁ fospropofol between the 11 migraine subjects and 9 healthy volunteers who received Fospropofol Disodium, 800 mg indicated that the distribution of the log of the ratio of AUC₁ propofol to AUC₁ fospropofol was different between migraine subjects and healthy volunteers, p=0.0367 (Wilcoxon rank-sum test).

Study Assessments

Intermittent Photic Stimulation Assessments

IPS assessments will be performed at prescreening if applicable, at screening, and at each treatment visit. At treatment visits, IPS sessions will be performed in the most sensitive eye condition, as determined at screening.

Prescreening (if applicable), screening, and predose IPS assessments will begin at approximately 8:00 to 8:30 am. Postdose IPS assessments will begin at 15 and 30 minutes and at 1, 2, 3, 4, and 6 hours after dosing (±5 minutes).

All IPS assessments for screening and during the study will be performed using the systematic protocol designed by Dorothee Kasteleijn. Kasteleijn-Nolst Trenite D G, Marescaux C, Stodieck S, Edelbroek P M, Oosting J. Photosensitive epilepsy: a model to study the effects of antiepileptic drugs. Evaluation of the piracetam analogue, levetiracetam. Epilepsy Res 1996; 25:225-230. The procedure will be as follows:

Photic Stimulator

The IPS will be carried out using the photic stimulator, Grass PS 33, with an un-patterned glass lamp and an intensity of 100 cd/m2/flash.

EEG Measurement with Video Monitoring

IPS session will be recorded with standard 19-21-channel EEG equipment including video monitoring and precise recording of duration and frequency of the flashes (sensor or connection with the photic stimulator).

Electrode Placement:

The international 10-20 system with 2 additional channels, one for eye-movements (to detect changes in eye condition more easily) and one for flash frequencies.

Montage:

A 19-21-channel recording system will be used with a bipolar derivation with emphasis on the parieto-temporal-occipital area (maximum and spreading of EA): The display montage will include T4-T6-O2-O1-T5-T3 and T4-P4-Pz-P3-T3, apart from 2×4 (8) frontal to occipital leads.

Settings:

-   -   Amplification: 7-10 microV/mm     -   High Frequency Filter: 35-70 Hz     -   Time constant: 0.3-0.6 sec     -   Display speed: 30 mm/sec

Methods:

The lighting will be dimmed but never completely darkened so as to permit observation of the subject, to control ocular fixation, and to note possible clinical ictal phenomena. Subjects will be seated with the photic stimulator at 30-cm distance from the nasion and will be asked to fixate on the center of the lamp.

Throughout the study the flash frequency will be recorded. The eye condition per stimulus for assessment purposes will also be recorded.

In order to enable discrimination between spontaneous and IPS-evoked discharges, at the beginning of the trial day the subject will be assessed for ≥2.5 minutes with eyes open and another 2.5 minutes with eyes closed without any stimulation.

Trains of flashes at constant frequency will be delivered for as close to 4 seconds as possible, and no more than 5 seconds, except when a photoparoxysmal response is elicited, when photic stimulation will be immediately stopped. Intervals between successive flash trains at a given frequency will last for at ≥5 seconds. Determination of the photosensitivity ranges will be assessed with separate trains of flashes of 4-5 seconds duration (or less if generalized epileptic activity occurs).

Flashes will be administered at standard frequencies of 2, 5, 8, 10, 13, 15, 18, 20, 23, 25, 30, 40, 50 and 60 Hz.

At the screening visit, each frequency will be assessed in 3 eye conditions (eyes closing, eyes closed, eyes open), commencing at 2 Hz. As soon as generalized EEG epileptiform activity appears, the stimulation for that particular frequency in a particular eye condition will be instantly terminated. For the other eye conditions, ascending frequencies will be used until generalized epileptiform activity is seen. This will determine the lower threshold frequencies for each eye condition.

Similar assessments will then be carried out starting at 60 Hz and descending through the standard frequencies. Again, the stimulator will be turned off immediately if a generalized response is seen to avoid occurrence of a seizure, and the sequence will be stopped at that point in that specific eye condition. For each eye condition, the upper threshold frequencies are thus determined.

The combination of lower and upper frequencies gives a total of 3 photosensitivity ranges, one per eye condition. If there is any doubt of the interpretation during any of the assessments (for example, blinking during the eyes open condition provoking epileptiform activity), the stimulation in the same eye condition will not be repeated. Photic stimulation will not be carried out between the upper and lower thresholds in order to minimize the risk of inducing a seizure. This method has been found to be the safest, as it prevents elicitation of seizures by avoiding stimulation of the subject at their most sensitive frequencies. The range for each subject will be recorded in the CRF.

Interpretation of Results:

The EEG technician performing the testing will remain blinded throughout the study.

The procedure for determining photosensitivity thresholds described here is interactive and requires immediate decisions by the Investigator during each assessment. The tracings will also be analyzed retrospectively to confirm that the limiting frequencies were the threshold for eliciting a response as defined above.

Blood Sample Collection and Processing

Blood samples will be collected and processed. The total volume of blood drawn from each subject over the course of this study will not exceed 540 mL and will not exceed 10.5 mL/kg over an 8-week period. In subjects of low body weight, the period between study visits may be extended (to up to 4 weeks) to meet this criterion. The maximum total amount of blood drawn includes standard screening and postdose clinical laboratory tests, pharmacokinetic analysis (fospropofol and propofol concentrations), ASM concentrations, and any additional treatment visits for evaluation of intermediate doses, revisiting a particular dose, or evaluation of different PK time points.

Sampling for Fospropofol/Propofol PK and ASM Assessment

Blood samples will be collected at each treatment visit for analysis of fospropofol and propofol PK, and separate samples will be drawn for assay of concomitant ASM levels.

Blood samples for fospropofol disodium/propofol PK and ASM levels will be drawn immediately after the end of the predose IPS session (within 30 minutes before dosing), at 10 minutes after dosing, and immediately after the end of each postdose IPS session (within 10 minutes after the start of the IPS measurement), with the exception that there will be no PK blood draw at 3 hours postdose. In case of an SAE or early withdrawal, a PK blood draw should be collected, if possible, at or near the time the subject reports the SAE or at the time of withdrawal.

Sample collections done outside the predefined time windows will not be considered as protocol deviations, since actual postdose sampling times will be used for PK and statistical analyses.

The time points of the PK sample collection may be changed, or an additional postdose time point may be added during Treatment Visit 1, 2, 3, or 4 or an additional visit. However, the total number of PK time points (including predose) will not exceed 9 per visit.

When appropriate, an indwelling i.v. catheter will be used for blood collection to avoid multiple skin punctures. Otherwise, blood samples will be collected by direct venipuncture.

In case of an SAE or early withdrawal, if possible, a PK blood draw should be performed at or near the time the subject reports the SAE or at the time of withdrawal from the study.

Safety Laboratory Assessments

Hematology samples will be drawn at screening and clinic check-out at each treatment visit. Hematology will include complete blood count with differential, hemoglobin, and hematocrit.

Serum chemistry samples will be drawn at screening and clinic check-out at each treatment visit. Serum chemistry assessments will include albumin, alanine aminotransferase, alkaline phosphatase, aspartate aminotransferase, calcium, chloride, carbon dioxide/bicarbonate, creatinine, glucose, phosphate, potassium, sodium, total bilirubin, total protein, and blood urea nitrogen (BUN).

Hepatitis B (HBs Ag), Hepatitis C (HCV) antibody, and HIV antigen and antibody detection will be performed at screening. (Reflex HCV RNA testing will be performed for any positive hepatitis C screening test. If the results of reflex testing are negative, the subject may be deemed eligible for the study.)

Urine for urinalysis will be collected at screening and clinic check-out at each treatment visit. Urinalysis will include macroscopic examination, pH, specific gravity, protein, glucose, ketones, bilirubin, occult blood, nitrite, urobilinogen, and leukocytes. Unless otherwise specified, microscopic examination will be performed on abnormal findings according to standard procedure.

For women, a serum pregnancy test will be performed at screening, and a urine pregnancy test will be performed at clinic check-in at each treatment visit.

A urine drug screen (amphetamines, methamphetamines, barbiturates, benzodiazepines, THC, cocaine, opiates, PCP, 3,4-methylenedioxy-methamphetamine (MDMA), methadone) and an alcohol breath test will be performed at screening and at clinic check-in at each treatment visit.

Other Safety Procedures and Assessments

Medical Surveillance and AE Monitoring

The Investigator is to be on site from approximately 30 minutes prior to each dosing until clinic discharge.

The study site is to be staffed to assess and manage potential risks that may occur with sedative-hypnotic agents. Subjects are to be continuously monitored for oxygen desaturation using a pulse oximeter with an alarm, and supplemental oxygen should be available. In addition, although these conditions are unlikely to occur at the selected dose of fospropofol disodium, subjects should be monitored for early signs of hypotension, apnea, or airway obstruction from approximately 30 minutes prior to dosing of study drug until clinic discharge. This role may be fulfilled by the Investigator or designee trained in airway management.

Safety parameters, including laboratory results, will be evaluated by the Investigator in the context of clinical trial safety. Any abnormal measurement is to be repeated if judged necessary by the Investigator. Further action to ensure subject safety may be taken at the Investigator's discretion.

Physical Examination

A complete physical and neurological examination will be performed at screening, and abbreviated physical and neurological examinations will be performed at clinic check-out at each treatment visit and at early termination, if applicable.

The complete physical examination at the screening visit will assess any physical abnormalities and will include at a minimum, assessments of the following body systems: general appearance, overall status of the head, ears, eyes, nose, throat (HEENT), neck, abdomen, lymph nodes, skin, cardiovascular/heart, pulmonary, musculoskeletal, and neurological (level of alertness [more detailed mental status not required unless indicated], speech, cranial nerves, motor strength and tone, cerebellar, sensory, deep tendon reflexes, and gait). Investigators should pay special attention to clinical signs related to previous serious illnesses.

Height and weight will also be measured and recorded at the screening visit.

The abbreviated physical examinations will assess general appearance, HEENT, cardiovascular, pulmonary, and neurological status. The neurological examinations are to consist of level of alertness and speech. Abbreviated physical examinations may be limited to recording change/no change from prior examinations, plus focused examination by system as directed by any AEs reported by the subject (where applicable) or any spontaneous symptom/complaint reported by the subject at the time of the examination.

Sheehan Suicidality Tracking Scale

The Sheehan Suicidality Tracking Scale (S-STS) is a prospective suicidality rating scale to be completed by the Investigator or his/her designate. The scale includes 16 questions that allow a longitudinal evaluation of treatment-emergent suicidal ideation and treatment-emergent suicidal behaviors.[25,26] Sheehan D V, Alphs L D, Mao L, et al. Comparative Validation of the S-STS, the ISST-Plus, and the C-SSRS for Assessing the Suicidal Thinking and Behavior FDA 2012 Suicidality Categories. Innov Clin Neurosci 2014; 11:32-46. Sheehan D V, Giddens J M, Sheehan I S. Status Update on the Sheehan-Suicidality Tracking Scale (S-STS) 2014. Innov Clin Neurosci 2014; 11:93-140.

The S-STS will be completed on a paper form at the site and will be administered at the screening visit, at clinic check-in, and at clinic check-out (discharge) for each treatment visit. The recall period at the screening administration will encompass the time period beginning 30 days prior to the screening visit; the recall period at each treatment visit will be the time period since the previous visit. The total score plus the subject's response to each item will be recorded.

At screening, any subject with a response greater than zero to any question must be excluded. At clinic check-in, any subject with a response greater than zero to any question other than Question 2 must be discontinued from the study and the event recorded as an AE, not treatment-emergent. Subjects with a response of 1 (“a little”) to Question 2 will be discontinued at the discretion of the Investigator. Subjects with a response greater than 1 on Question 2 will be discontinued.

For each administration of the S-STS, the Investigator will immediately evaluate a subject with any response greater than zero to determine if that subject is at risk of self-harm or suicide. If this is the case, the Investigator must take appropriate measures to ensure the subject's safety and arrange for an appropriate mental health evaluation.

A 12-lead ECG will be performed at screening and at clinic check-out on Treatment Day 4 (or at early termination or check-out of an additional visit, if applicable). Corrected QT interval (QTc) will be recorded.

Pulse oximetry will be recorded at screening and continuously monitored at each treatment visit from at least 15 minutes prior to the predose IPS assessment until discharge from the clinic. The pulse oximeter is to have an alarm set to give both audible and visual notifications when SpO2 drops to 90% or below. If the alarm signals, the subject should be aroused. Nasal oxygen should be considered if SpO2 remains at 90% or lower after stimulation.

At each treatment visit, SpO2 values will be recorded from the continuous monitor within 15 minutes before the predose IPS assessment, postdose within 10 minutes before each IPS assessment, between IPS assessments at 30-minute intervals (±10 minutes) until 6 hours after dosing, and at clinic check-out.

Vital signs (BP, HR, RR, and temperature) are to be assessed at screening and at each treatment visit within 15 minutes before the predose IPS assessment, postdose within 10 minutes before each IPS assessment, between IPS assessments at 30-minute intervals (±10 minutes) until 6 hours after dosing, and at clinic check-out. The subject should be in a seated or semi-reclined position for at least 5 minutes before vital sign assessments. Vital sign assessments may be repeated at the discretion of the Investigator.

Level of sedation will be assessed using a visual analog scale for sedation at screening, and at each treatment visit within 15 minutes before the predose IPS assessment, postdose within 10 minutes before each IPS assessment, and at clinic check-out. If degree of sedation is a concern, the duration of confinement may be extended, and safety monitoring may continue at the discretion of the Investigator.

The visual analog scale (VAS) for sedation is a distinct 100-millimeter line anchored on the left end at full degree of impairment and on the right end at no degree of impairment, where indication of the degree of impairment perceived at the time of assessment is captured by marking the appropriate position on the line between the anchor points. The measured distance of the mark from the left anchor will be recorded in millimeters

Sedation will be measured using a 100-mm linear visual analog scale (VAS). The subject will be given 2 scales, 1 anchored by “Sedated” and “Alert, the other by “Sleepy and “Awake” and asked to “Place a vertical mark on the line indicating your feelings RIGHT NOW”. The location of the mark will be measured at a later time and the results will be recorded in mm from the left on the appropriate CRF.

An example of the subject VAS is provided below. The paper scales will be provided to the site, and only originals can be used for subject assessment. Photocopies cannot be provided for subject assessment.

Analytical Methodology

Samples will be transported to the bioanalytical facility packed on sufficient dry ice to keep them frozen for at least 72 hours.

Safety laboratory values and ASM concentrations will be analyzed using validated methods. Fospropofol and propofol concentrations will be analyzed in plasma samples using a validated method and in accordance with the current regulations and guidelines in place for industry, including guidances on Bioanalytical Method Validation, Good Laboratory Practice (GLP) for Nonclinical Laboratory Studies, and GCP ICH E6(R2).

Statistical Considerations

A complete description of the statistical analyses to be performed for the safety, tolerability, PK, and photoparoxysmal response data will be presented in a Statistical Analysis Plan (SAP).

Safety and Tolerability

Safety and tolerability data will be reported using descriptive statistics. Summary statistics for TEAEs will be reported. Changes from baseline values in vital signs, ECG, and clinical laboratory parameters will be reported.

PK

Summary statistics will be used to describe the PK profile of both fospropofol and propofol. Summary statistics will include at minimum arithmetic and geometric means for AUC0-t, AUC0-inf, and Cmax. Tmax will be characterized by median and range. Exploratory analyses may be performed in an effort to characterize the influence of covariates on PK.

The observed concentrations of concomitant ASMs will be listed and presented as summary statistics. Pharmacokinetic parameters for concomitant ASMs may be calculated, listed, and presented as summary statistics if feasible.

Exploratory analyses may be performed in an effort to characterize the effect, if any, of fospropofol disodium on concentrations of concomitant ASMs. Such analyses could provide useful information as to the potential for drug-drug interactions requiring further evaluation in the subsequent development of fospropofol disodium in the treatment and prevention of epileptic seizures.

Photoparoxysmal Response

Descriptive statistics will be presented including the means and standard deviations of photosensitivity range for each subject, for each day. Graphical displays of the data for each subject will allow exploration of inter- and intra-subject variability.

Example B2: Bioavailability Studies

The bioavailability of propofol from the fospropofol-containing dosage forms is assessed in dogs using the following general protocol.

The dogs used in the studies have the following characteristics:

-   -   Strain: Beagle     -   Condition: Purpose-bred, non-naïve     -   Source: Marshall Farms. North Rose, N.Y.     -   Number of Males: 6 (plus 1 alternate)     -   Target Age at the Initiation of Dosing: At least 8 months.     -   Target Weight at the Initiation of Dosing: 6 to 13 kg

All animals used in the studies have documentation of immunization for parvovirus, distemper, adenovirus type 2, parainfluenza, Bordetella, papilloma, and rabies.

Animals are identified with a tattoo or a subcutaneously implanted electronic identification chip.

Each animal is inspected by a clinical veterinarian upon receipt. Animals judged to be in good health are placed immediately in acclimation for at least 10 days.

Animals judged to be suitable for testing are assigned to groups randomly based on body weight stratification into a block design using computer program. Animals are arbitrarily reassigned to a different group at the discretion of the study director based on acclimation data.

The animals are dosed as follows:

-   -   Dose Route: Tablet; Acidified Tablet     -   Frequency: Once daily; single administration         -   Method: The first day of dosing is designated as Day 1             (exception: alternate animals used for replacement after Day             1 assume the day of the animal being replaced).     -   Tablet Administration: A single dose of the test article is         administered orally via tablet.         -   Each subject receives 1 (600 mg) tablet. Doses are             irrespective of body weight.         -   In studies wherein the dogs are pretreated with pentagstrin,             the pentagastrin is administered intravenously before the             dogs are administered the fospropofol-containing tablet.

In a separate study, the dogs are orally administered a solution containing 30 mg/mL fospropofol at a dose of 160 mg/kg in water rather than a tablet.

Bioanalytical Methods:

-   -   Venipuncture from a jugular vein (saphenous or cephalic vein is         used, if necessary).     -   Target Volume (mL): Approximately 1 mL/time point collected         without anesthesia.     -   Anticoagulant: Sodium Heparin     -   Prior to blood collection, approximately 0.05 mL of 200 mg/mL of         sodium orthovanadate (SOV) solution is added to the heparinized         blood collection tubes to prevent ex vivo conversion via         alkaline phosphatase.     -   Special Requirements: After collection, blood collection tubes         are kept on wet ice until centrifugation within 30 minutes of         collection.     -   Processing: Plasma Samples are mixed gently and centrifuged         within 30 minutes of collection. The samples are centrifuged at         2-8° C. and the resultant plasma is separated, transferred to         duplicate uniquely labeled polypropylene tubes, and kept on wet         ice until transferred to storage. Samples are stored in a         freezer set to maintain a target of −70° C.     -   Bioanalytical samples are analyzed for concentration of test         article (fospropofol) and specified metabolites (propofol) using         a validated analytical procedure.

The pharmacokinetic results demonstrate that administering fospropofol together with an acid, such as in the acidified tablets, results in increased propofol Cmax and AUC∞ when compared to the dose adjusted exposure seen with the oral solution. See FIG. 28; Table B9. This effect is seen using both ascorbic acid and tartaric acid as the tablet acidifiers.

In addition, the results demonstrate that administration of the acidified tablets with pentagastrin pretreatment results in increased plasma propofol Cmax and AUC∞ compared to the plasma propofol Cmax and AUC∞ observed upon administration of a control tablet (i.e., with no acidifier) with pentagastrin pretreatment. See FIG. 29; Table B9. Pentagastrin pretreatment acidifies the subject's stomach contents to an acidity comparable to that of normal human stomach contents.

In addition, these results demonstrate that co-administration of fospropofol disodium with tartaric acid without pentagastrin pretreatment results in increased plasma propofol Cmax and AUC∞ compared to the plasma propofol Cmax and AUC∞ observed upon administration of a control tablet (i.e., with no acidifier) with pentagastrin pretreatment. See FIG. 30; Table B9.

The experiments described above surprisingly demonstrate that oral administration of fospropofol together with a pharmaceutically acceptable acid increases the plasma propofol Cmax and AUC∞ relative to controls in which fospropofol is orally administered without an acidifier. Moreover, this effect is seen with multiple acids (e.g., ascorbic acid, tartaric acid) and is seen under conditions expected in human subjects. Thus, the disclosed invention solves the problem of providing an oral dosage form that can provide useful propofol pharmacokinetics.

These results also demonstrate that co-administration of fospropofol disodium with a pharmaceutically acceptable acid can result in decreased variability in Cmax and AUC∞ relative to administration without acid.

In a separate study, the food effect upon administering the compositions of the disclosure is examined. Two groups of dogs, one fasted and one fed, are administered either the 600 mg fospropofol acidified composition comprising ascorbic acid (i.e., composition A2) or 600 mg (3×200 mg) of fospropofol control composition (i.e., HMPC capsule; no acidifier). The fasted group is fasted (no food, only water) overnight prior to being administered the fospropofol dose. The maximum individual fasting period does not exceed 24 hours. The fasted group is pretreated with pentagastrin. The fed group is given a high calorie meal and the dose of fospropofol is given within an hour of eating the meal. The fed group is not pretreated with pentagastrin.

These results demonstrate that the acidified compositions demonstrate a food effect and that the food effect differs from that observed with the non-acidified control composition. See FIG. 31; Table B10.

Both the acidified tablet and the control composition exhibit a negative food effect on the bioavailability of fospropofol.

The extent of the food effect is modulated depending on the dosage form.

In the control compositions, the mean fospropofol Cmax (fed) is 17% of the mean fospropofol Cmax (fasted). In the acidified tablet, the mean fospropofol Cmax (fed) is 102% of the mean fospropofol Cmax (fasted).

In the control compositions, the mean total fospropofol Cmax (fed) is 30% of the mean total fospropofol Cmax (fasted). In the acidified tablet, the mean total fospropofol Cmax (fed) is 71% of the mean total fospropofol Cmax (fasted).

In the control compositions, the mean total fospropofol AUC_(0-∞) (fed) is 30% of the mean total fospropofol AUC_(0-∞)(fasted). In the acidified tablet, the mean total fospropofol AUC_(0-∞)(fed) is 71% of the mean total fospropofol AUC_(0-∞)(fasted).

Instrumental Methods

XRPD diffractograms were collected on a Bruker D8 diffractometer using Cu Ka radiation (40 kV, 40 mA) and a 0-20 goniometer fitted with a Ge monochromator. The incident beam passes through a 2.0 mm divergence slit followed by a 0.2 mm anti-scatter slit and knife edge. The diffracted beam passes through an 8.0 mm receiving slit with 2.5° Soller slits followed by the Lynxeye Detector. The software used for data collection and analysis was Diffrac Plus XRD Commander and Diffrac Plus EVA respectively.

Samples were run under ambient conditions as flat plate specimens using powder. The sample was prepared on a polished, zero-background (510) silicon wafer by gently pressing onto the flat surface or packed into a cut cavity. The sample was rotated in its own plane. The details of the standard Pharmorphix data collection method are:

-   -   Angular range: 2 to 42° 20     -   Step size: 0.05° 20     -   Collection time: 0.5 s/step (total collection time: 6.40 min)

XRPD diffractograms were also collected on a PANalytical Empyrean diffractometer using Cu Ka radiation (45 kV, 40 mA) in transmission geometry. A 0.5° slit, 4 mm mask and 0.04 rad Soller slits with a focusing mirror were used on the incident beam. A Pacel30 detector, placed on the diffracted beam, was fitted with a receiving slit and 0.04 rad Soller slits. The software used for data collection was X'Pert Data Collector using X'Pert Operator Interface. The data were analysed and presented using Diffrac Plus EVA or HighScore Plus.

Samples were prepared and analysed in either a metal or Millipore 96 well-plate in transmission mode. X-ray transparent film was used between the metal sheets on the metal well-plate and powders (approximately 1-2 mg) were used. The Millipore plate was used to isolate and analyse solids from suspensions by adding a small amount of suspension directly to the plate before filtration under a light vacuum. The scan mode for the metal plate used the gonio scan axis, whereas a 20 scan was utilised for the Millipore plate. The details of the standard screening data collection method are:

-   -   Angular range: 2.5 to 32.0° 20     -   Step size: 0.0130° 20     -   Collection time: 12.75 s/step (total collection time of 2.07         min)

Solution State NMR

¹H NMR and/or ¹³C NMR spectra were collected on a Bruker 400 MHz instrument equipped with an auto-sampler and controlled by a DRX400 console. Samples were prepared in DMSO-d₆ solvent, unless otherwise stated. Automated experiments were acquired using ICON-NMR configuration within Topspin software, using standard Bruker-loaded experiments (¹H, ¹³C {¹H}, DEPT135). Off-line analysis was performed using ACD Spectrus Processor.

Differential Scanning calorimetry (DSC)

DSC data were collected on a TA Instruments Q2000 equipped with a 50 position auto-sampler. Typically, 0.5-3 mg of each sample, in a pin-holed aluminium pan, was heated at 10° C./min from 25° C. to 300° C. A purge of dry nitrogen at 50 ml/min was maintained over the sample. The instrument control software was Advantage for Q Series and Thermal Advantage and the data were analysed using Universal Analysis or TRIOS.

Thermal Gravimetric Analysis

TGA data were collected on a TA Instruments Discovery TGA, equipped with a 25 position auto-sampler. Typically, 5-10 mg of each sample was loaded onto a pre-tared aluminium DSC pan and heated at 10° C./min from ambient temperature to 350° C. A nitrogen purge at 25 ml/min was maintained over the sample. The instrument control software was TRIOS and the data were analysed using TRIOS or Universal Analysis.

Example C2 Preparation of Fospropofol Procedure 1

Fospropofol disodium (100 mg, ±1 mg) was weighed into 3 HPLC vials and dissolved in water (5 vol. 0.5 ml) at RT. Hydrochloric acid, sulfuric acid or phosphoric acid (2.1 eq. 1 M in THF) was added to the samples and stirred for 5 minutes and no solids were observed. Samples were cooled to 5° C. and still no solids were observed. The sample containing hydrochloric acid was selected to extract the product using DCM (3×extraction with 0.5 ml DCM). The organic layers were collected and concentrated under rotary evaporator at 50° C. resulting in a clear colourless oil. This oil was analysed by 1H NMR, HPLC and scanning ion chromatography.

Procedure 2

Fospropofol disodium (2.0 g) was dissolved in water (5 vol) at RT. Once a clear solution was obtained HCl (2.1 eq., 0.5 Min water) was added and a cloudy solution was formed. The sample was transferred to a separating funnel and DCM (30 ml) added to extract the free acid but instead formed a thick white emulsion with no phase separation. DCM (130 ml) was added to try and increase phase separation and water (100 ml) was added to solubilise any NaCl precipitating out of solution. The thick white emulsion remained so THF was added to disrupt the emulsion, resulting in separation of the aqueous and organic phases both cloudy solutions. The organic layer was collected and the aqueous layer washed with THF:DCM 25:75 (2×40 ml). The organic layer was concentrated under vacuum resulting in a clear oil.

Example C3

The following procedure was used to make the potassium (from KOH), diethylamine, t-butylamine, ethylene diamine, benzathine, piperazine, ethanolamine, diethanolamine, ammonium (from NH₄OH), tromethamine, benethamine, and histidine salts.

Fospropofol free acid (25 mg) was dissolved in EtOH (20 vol, 500 μl) at RT. The solutions were treated with the corresponding base (2 mol eq., added as a stock solution) at 25° C. After 10 minutes at 25° C., the mixtures were cooled to 5° C. at 0.1° C./min. After 48 hrs at 5° C. solids were filtered, air dried and analysed by XRPD, solutions were allowed to evaporate at RT. Solids formed from evaporation were analysed by XRPD, gums and oils were placed under vacuum for 3 hours. Solids were analysed by XRPD and remaining gums and oils matured at 50° C./RT in 4 hours temperature cycles for 48 hrs.

XRPD was again taken after 7 days storage at 40° C./75% RH. Form II of the diethylamine salt and Form II of the ethanolamine salt were formed by conversion of Form I of the respective salts after 7 days storage at 40° C./75% RH.

Example C4

The following procedures were used to make the calcium (from CaCl₂), magnesium (from MgCl₂), and zinc (ZnCl₂) salts.

Small Scale: Fospropofol disodium (50 mg) was dissolved in water (10 vol, 500 μl). The solutions were treated with the corresponding base (1 mol eq., added as a stock solution). Additional ethanol (500 μl) was added after the formation of a thick suspension and samples stirred for 1 hour before being filtered and dried in a vacuum oven for 2 hours at 40° C. Form I of the calcium salt and Form I of the zinc salt were produced under these conditions.

Form II of the calcium salt was produced from Form I of the calcim salt after 7 days storage at 40° C./75% RH.

Scale Up: Fospropofol disodium (500 mg) was dissolved in water (10 vol, 5 ml). The solutions were treated with the corresponding base (1 mol eq. CaCl2, MgCl2, or ZnCl2). Additional ethanol* (5 ml) was added after the formation of a thick suspension and samples stirred for 1 hour before being filtered and dried in a vacuum oven for 2 hours at 40° C. *ethanol (5 ml) was added three times for the sample containing the calcium counter ion as thick precipitate continued to stop stirring. This procedure produced Form III of the calcium salt and Form II of the zinc salt. ion chromatography of the product salts indicated that the calcium and magnesium salts each contained 1 eq. of the metal counterion, and the zinc salt contained 2 eq. of the metal counterion.

Example C5 Preparation of Ethylene Diamine Salt

The free acid (500 mg) was dissolved in EtOH (20 vol, 10 ml) at 50° C. The solution was treated with ethylene diamine (2 mol eq.) at 50° C. The sample was cooled to 5° C. at 0.1° C./min. After 48 hrs at 5° C. solids were filtered and dried in a vacuum oven for 2 hours at 40° C.

Example C6—Intrinsic Dissolution Rate at pH 4.5

Intrinsic Dissolution Rate was measure in GI tract buff (pH—4.5 buffer): 2.99 g sodium acetate trihydrate was dissolved in 14.0 ml 2N acetic acid in a 1000 ml volumetric flask, and then made to volume with deionised water.

Data were collected on a Sirius inform instrument fitted with a dual UV DipProbe attachment and Ag/AgCl combination pH electrode. The electrode was calibrated using the four plus parameters derived from a blank titration. The base titrant was standardised by titration with TRIS. 0.5 M HCl and NaOHaqueous solutions were used as the acid and base titrants respectively for the testing. Stirring was facilitated by a dual overhead stirrer to allow thorough mixing within the vessel, and media was introduced via a capillary bundle attached to a dispensing bank comprised of six precision dispensing units. A Peltier heating jacket was used to maintain the temperature of the titration vessel. Discs were introduced to the vessel via the tablet picker housed in the probe arm, after the desired temperature of the media had been reached. Sirius inform Assay Design, Control and Refine software were used to design, run and refine data respectively.

The reference sample was prepared as a 20.1 mM stock solution in water. One MEC data sets were then collected using five additions each of the water stock using 250, 500 and three times 750 μl aliquots, respectively. UV Spectra were then collected after each addition of the water stock to build a multi-point MEC calibration, using a 20 mm path length probe. The MEC data set was then imported into the dissolution data files in order to convert the UV absorbance measured to concentration. The concentration range for UV data collected was 124.8 μM—1.4 mM. MEC data were collected at 37° C. to match the dissolution experiments. Same MEC data was used as for faSSGf IDR experiments due to there being no change in the UV profile at this pH.

Intrinsic Dissolution Rate (IDR): Approximately. 10-20 mg of the sample was compressed in a 3 mm disc recess, under 100 kg for 2 minutes, with greaseproof paper on the compression base, to form nondisintegrating discs. The discs were then plugged with a bung so that only one surface was exposed to the media during analysis and transferred to the Sirius inform dissolution apparatus. Analysis was performed at 37° C. in 36 ml water and 4 ml GI media with the pH set to 4.5, for 1 hour with UV spectra collected every 10 seconds. A stir speed of 100 rpm was used with a 20 mm path length probe. The IDR was calculated based on the surface area of the 3 mm disc recess used (7.07 mm2 surface area). XRPD analysis was performed on all samples, both after compression of the material into the disc recess, and post dissolution analysis to observe any change in form. All analysis was performed using XRPD 2.

X-Ray Powder Diffraction (XRPD2): XRPD diffractograms were collected on a Bruker AXS C2 GADDS diffractometer using Cu Ka radiation (40 kV, 40 mA), an automated XYZ stage, a laser video microscope for auto sample positioning and a Vantec-500 2-dimensional area detector. X-ray optics consists of a single Gobel multilayer mirror coupled with a pinhole collimator of 0.3 mm. The beam divergence, i.e. the effective size of the X-ray beam on the sample, was approximately 4 mm. A 9-9 continuous scan mode was employed with a sample—detector distance of 20 cm which gives an effective 29 range of 1.5°-32.5°. The sample was exposed to the X-ray beam for 120 seconds under ambient conditions. The software used for data collection and analysis was GADDS for Win7/XP and Diffrac Plus EVA respectively.

The results are shown in the Table C1 below.
